Endor I was a star, one of a binary pair found at the heart of the Endor system, situated within the Moddell sector of the Outer Rim Territories. Endor II was the name of the other star in this binary system, and they were both circled by the gas giant known as Endor.
The reference book Star Wars: Absolutely Everything You Need to Know, published in 2015, provided the initial mention of Endor I within the contemporary Star Wars canon. Conversely, within the Star Wars Legends timeline, the Endor system possessed a solitary sun, which was designated as Ibleam.
